I. PREFACE
This chapter describes disassembly and reassembly procedures of the printer.
The service technician is to find the cause of the failure according to the "Chapter 4
Troubleshooting" and to follow the disassembly procedures in this chapter to replace the defec-
tive part(s). Replacement of consumable part(s) is also to be conducted according to the proce-
dures described in this chapter.
Note the following precautions during disassembly or reassembly.
1. At disassembly, reassembly, or transportation of the printer, remove the cartridges and sec-
ondary transfer roller if necessary. When removing the cartridges, even for a short period,
put them in their protective bag to prevent light from affecting them.
2. CAUTION: Before serving the printer, unplug the power cord from the electrical outlet.
When unplugging the power cord, be sure to turn off the power switch in advance after mak-
ing sure that the engine has completed its operation.
3. Reassembly is the reverse of disassembly unless otherwise specified.
4. Note the lengths, diameters, and locations of screws as you remove them. When reassem-
bling the printer, be sure to use them in their original locations.
5. Do not operate the printer with any parts removed.
6. Discharge electrical static from your body by touching the metallic areas of the printer before
handling the PCBs to prevent causing damage by the difference in static charge at that time.
7. Do not touch the rubber areas of the pick-up roller and the secondary transfer roller with
bare hands.
